In New Zealand a DNA extracted from a fossil of a moa suggests a different geological history of the country. This extraction suggests that New Zealand was geologically much different than they thought. They now believe that it had marine barriers, mountains and glacial cycles that scientists at first did not recognize. The moa were among hundreds of birds that inhabited the island over a million years ago. Most birds of the time were flightless weighing 250kg and over.
There were nine species of moa on the islands which were all relatively the same. With the DNA scientists were able to create the evolutionary patterns which in return told more about the environment of New Zealand. Changes in the bone structure of the moa and other body parts they drew clues about the habitat they lived in. It is remarkable how scientists can draw clues from over a million year old fossils that suggest differences in the geology. This type of research I believe shows that anything is possible in science.
